GBB:TFA: "Doctors have said I might have the Scottish accent for the rest of my life, or it might just disappear overnight but I don't think it's going anywhere fast."

She wouldn't have said "don't". It would have been "dunna"

Yeah, because her head injury didn't actually result in her speech transforming from Canuck to Scots... it lead to a speech impairment that she and people around her perceive as resembling Scots. That's why this "syndrome" creates accents, not actual language switches.

Also, from TFA:"I could have ended up with any accent - French, Spanish, even Klingon - but I got Scottish. It was definitely a sign."The accident has completely turned my life around. "I strongly believe it was a message telling me this is how things were meant to be."

It's not a sign. It's a situation that you are interpreting as meaningful, dearie. Humans are great at that sort of thing - reading meaning where there is none independent of their own interpretations.

"Sharon, a mum-of-two who ran a horse-riding school, says the disorder is a blessing and led to her tracing her family's Scottish roots."

Oh, BULLSHIAT. Accents are not in the blood. I have known people who put on accents for attention too, and one also said that she "gets a British accent when she drinks because she has British blood in her". She never spent any time there, was not raised by anyone with an accent, and only remembered to speak with the phony accent once in a while.

The reason that this "only affects 60 people in the world" is that there are only 60 doctors stupid enough to fall for the attention whoring.
